    Abstract: A small volume laboratory filter having a thin rectangular body and coaxial inlet and outlet sleeves connected to opposite ends thereof. A very thin filter cavity is formed in the body and lies in a plane inclined slightly to the common axis of the inlet and outlet sleeves. The cavity is divided by a filter membrane into extremely thin chambers, one communicating with the inlet sleeve and the other with the outlet sleeve. A rigid package for the filter is sealed across one end by a flexible cover which when stripped from the package exposes the inlet sleeve so that it may be readily engaged by a syringe nipple or other fluid source without the user having to touch the filter. When the inlet sleeve is engaged, the filter may be withdrawn from the package.

    Abstract: A multi-channel pipetter has a U-shaped housing with horizontal upper and lower arms and an interconnecting hand grip portion. A plurality of nozzles that serve to support replaceable tips are mounted on the lower arm in a vertical orientation are connected by a flexible tubing that extends upwardly through the grip portion to a circular array of cylinders disposed horizontally in the upper arm. A piston- cylinder-volume setting mechanism is horizontally disposed in the upper arm. The mechanism is actuated by a trigger on the hand grip portion and the volume is controlled by a micrometer head which operates a stop within the upper arm. A tip ejector is mounted in the lower arm which provides substantial mechanical advantage for stripping the tips from the nozzles.

    Abstract: Microplates and methods for manufacturing microplates. The microplate is designed to allow UV radiation to pass through the bottom wells of the microplate so that the microplate can be used for assaying samples by use of UV absorbance. In one embodiment, the microplate comprises at least first and second wells, each well having a UV permeable bottom. In another embodiment, the microplate comprises a frame having an upper portion and a lower portion contiguous with the upper portion and a sheet disposed between the upper portion and the lower portion and defining the bottom of at least one well of the microplate. One embodiment of the method includes steps of inserting a sheet of UV permeable material into a mold cavity that includes sections shaped to form the sidewalls of the plurality of wells, injecting molten plastic material into the mold cavity, and cooling the plastic material to form the microplate with the plastic material forming the sidewalls of each of the first and second wells and the sheet of UV permeable material forming the bottom of each of the first and second wells. Another embodiment of the method includes providing an upper plate defining sidewalls of at least one well, adhering an intermediate layer to the upper plate and adhering a sheet of UV permeable material to the intermediate layer. A further embodiment of the method includes inserting a sheet of material having at least one hole into a mold cavity, injecting a molten plastic material into the mold cavity and cooling the plastic material to form a microplate.

    Abstract: A filter for a centrifuge tube including a pressure filter (18) for separating a mixture under centrifugal force. The filter tube (10) is adapted to fit within the upper portion of a standard plastic centrifuge tube (51). The filter tube (10) has a pressure filter (18) at its lower end and an opening (14) at its upper end adapted to be sealed by a cap (55) extending from the centrifuge tube to hold the filter tube (10) securely in position within the centrifuge tube (51). The filter tube (10) is filled with a mixture of permeable and non-permeable materials and when the composite centrifuge tube (51) and filter tube (10) is spun in the centrifuge, the centrifugal force causes the permeable materials to flow through the filter (18) and collect in the bottom (52) of the centrifuge tube (51) while the non-permeable materials are retained in the filter tube (10).
